Code:

But it when I try to compile it with VS C++ 2010 on Windows 7, I get complain:

    The std headers can include one another, but it’s not mandated which ones should include which. Your safest bet is to have:

    #include <iostream>
#include <string>

    at the top of the file.

    My guess is the compilers that did compile the code had these headers included indirectly, whereas VS doesn’t. Which is fine. The programmer is responsible for including all headers he needs.
